[   15.998715] 

[terpstra]

Right. This is probably because the current kernel does not support the DTS output by the current freedom repository. We need to fix this.

[terpstra]

The bug is actually in the freedom repository, which we are also currently working on, so we will fix it there in the next week.

[xubaqian]

@terpstra Thanks, sir. I found the newest freedom commits on May 16, 2018 still didn't work. Would you please remind me when you fix this bug? Thanks again!

[terpstra]

Yeah, sorry for my overly optimistic time estimate. It seems this is probably not going to happen immediately. If you want to diagnose it yourself, try to find out which function the kernel is crashing in from the sepc register. We would like to ideally convert our existing boot process from the HiFive Unleashed boards to also work on the FPGA, but I'm not sure when someone will take up this task.

[xubaqian]

@terpstra OK. So is there any earlier commit available? Even in 2017.

[xubaqian]

@terpstra Well, I have found one and it works. Thanks
